This book was released on 2021 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the widespread use of the Global Positioning System (GPS) for positioning, navigation, and timing (PNT), concerns have been expressed that a disruption of GPS might require a national investment in backup capabilities. The authors assess the costs associated with realistic threats to domestic, nonmilitary uses of GPS, and review possible additions to the PNT ecosystem in light of those costs. When the ability of individuals and organizations to adapt to and use existing alternatives and workarounds is taken into account, our analysis suggests that the costs of GPS disruption, while real, would not be as high as is sometimes assumed. When actual GPS jamming events have occurred in the past, users have felt the effects but generally managed to cope without disastrous consequences. Also, we consider it unlikely that any event short of nuclear war would deny all satellite navigation to the entire United States for more than a few days. At the same time, any system that could entirely replace GPS would be comparatively much more expensive than the damages it would mitigate. Therefore, it is difficult to justify extensive investment in more GPS backups, although industry or government might well invest in PNT systems for their other merits, not just as a backup for GPS disruption per se. For example, the federal government is already investing in a system that will improve PNT for phone users in important urban areas, and this incidentally could also serve as a GPS backup.

Download or read book GPS Disruptions written by Joseph Kirschbaum and published by . This book was released on 2013-12-07 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Global Positioning System (GPS) provides positioning, navigation, and timing data to users worldwide and is used extensively in many of the nation's 16 critical infrastructure sectors, such as communications and transportation. GPS is also a key component in many of the modern conveniences that people rely on or interact with daily. However, sectors' increasing dependency on GPS leaves them potentially vulnerable to disruptions. This report examined (1) the extent to which the Dept. of Homeland Security (DHS) has assessed the risks and potential effects of GPS disruptions on critical infrastructure; (2) the extent to which the Dept. of Transportation (DOT) and DHS have developed backup strategies to mitigate GPS disruptions; and (3) what strategies, if any, selected critical infrastructure sectors employ to mitigate GPS disruptions and any remaining challenges.

Download or read book Defense Against the Dark Arts in Space written by Todd Harrison and published by Rowman & Littlefield. This book was released on 2021-10-20 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proliferation of counterspace weapons across the globe often calls into question what can be done to best protect satellites from attack. This analysis from the CSIS Aerospace Security Project addresses different methods and technologies that can be used by the United States government, and others, to deter adversaries from attack. A wide range of active and passive defenses are available to protect space systems and the ground infrastructure they depend upon from different types of threats. This report captures a range of active and passive defenses that are theoretically possible and discusses the advantages and limitations of each. A group of technical space and national security experts supported the analysis by working through several plausible scenarios that explore a range of defenses that may be needed, concepts for employing different types of defenses, and how defensive actions in space may be perceived by others. These scenarios and the findings that resulted from subsequent conversations with experts are reported in the penultimate chapter of the report. Finally, the CSIS Aerospace Security Project team offers conclusions drawn from the analysis, actionable recommendations for policymakers, and additional research topics to be explored in future work.

This book was released on 2016-08-30 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is not yet 60 years since the first artificial satellite was placed into Earth orbit. In just over a half century, mankind has gone from no presence in outer space to a condition of high dependence on orbiting satellites. These sensors, receivers, transmitters, and other such devices, as well as the satellites that carry them, are components of complex space systems that include terrestrial elements, electronic links between and among components, organizations to provide the management, care and feeding, and launch systems that put satellites into orbit. In many instances, these space systems connect with and otherwise interact with terrestrial systems; for example, a very long list of Earth-based systems cannot function properly without information from the Global Positioning System (GPS). Space systems are fundamental to the information business, and the modern world is an information-driven one. In addition to navigation (and associated timing), space systems provide communications and imagery and other Earth-sensing functions. Among these systems are many that support military, intelligence, and other national security functions of the United States and many other nations. Some of these are unique government, national security systems; however, functions to support national security are also provided by commercial and civil-government space systems. 
The importance of space systems to the United States and its allies and potential adversaries raises major policy issues. National Security Space Defense and Protection reviews the range of options available to address threats to space systems, in terms of deterring hostile actions, defeating hostile actions, and surviving hostile actions, and assesses potential strategies and plans to counter such threats. This report recommends architectures, capabilities, and courses of action to address such threats and actions to address affordability, technology risk, and other potential barriers or limiting factors in implementing such courses of action.

Download or read book Disaster Resilience written by National Academies and published by National Academies Press. This book was released on 2012-12-29 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: No person or place is immune from disasters or disaster-related losses. Infectious disease outbreaks, acts of terrorism, social unrest, or financial disasters in addition to natural hazards can all lead to large-scale consequences for the nation and its communities. Communities and the nation thus face difficult fiscal, social, cultural, and environmental choices about the best ways to ensure basic security and quality of life against hazards, deliberate attacks, and disasters. Beyond the unquantifiable costs of injury and loss of life from disasters, statistics for 2011 alone indicate economic damages from natural disasters in the United States exceeded $55 billion, with 14 events costing more than a billion dollars in damages each. One way to reduce the impacts of disasters on the nation and its communities is to invest in enhancing resilience-the ability to prepare and plan for, absorb, recover from and more successfully adapt to adverse events. Disaster Resilience: A National Imperative addresses the broad issue of increasing the nation's resilience to disasters. This book defines "national resilience", describes the state of knowledge about resilience to hazards and disasters, and frames the main issues related to increasing resilience in the United States. It also provide goals, baseline conditions, or performance metrics for national resilience and outlines additional information, data, gaps, and/or obstacles that need to be addressed to increase the nation's resilience to disasters. Additionally, the book's authoring committee makes recommendations about the necessary approaches to elevate national resilience to disasters in the United States. Enhanced resilience allows better anticipation of disasters and better planning to reduce disaster losses-rather than waiting for an event to occur and paying for it afterward. Disaster Resilience confronts the topic of how to increase the nation's resilience to disasters through a vision of the characteristics of a resilient nation in the year 2030. Increasing disaster resilience is an imperative that requires the collective will of the nation and its communities. Although disasters will continue to occur, actions that move the nation from reactive approaches to disasters to a proactive stance where communities actively engage in enhancing resilience will reduce many of the broad societal and economic burdens that disasters can cause.
Download or read book Global Navigation Space Systems written by Royal Academy of Engineering (Great Britain) and published by . This book was released on 2011 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Global Positioning System (GPS) is currently the most widely used and best known example of GNSS. Today, the relative ease of use of GPS in-car navigation systems means that many motorists rely entirely on GPS for navigation and if they have a road map as a back-up, it is not likely to have been used or updated in a long time. This is a trivial example of reliance on GPS with neglect of back-up systems, but the use of GPS signals is now commonplace in data networks, financial systems, shipping and air transport systems, agriculture, railways and emergency services. Safety of life applications are becoming more common. One consequence is that a surprising number of different systems already have GPS as a shared dependency, so a failure of the GPS signal could cause the simultaneous failure of many services that are probably expected to be independent of each other. The European Commission has estimated that, already, 6-7% of GDP in Western countries is already dependent on satellite radio navigation, so this study into our reliance on GNSS and potential vulnerabilities is both important and timely. Such widespread use of GNSS derived data within our economies means that the secure provision of PNT data is now a matter of national security as well as a major economic asset.
